Publisher's Summary

Since logic derives from postulates, it never has, and never will, change a postulate. And a religious belief is a system of postulates...so how can a man fight a native superstition with logic in order to save the inhabitants of an entire planet? A classic science fiction novelette by H. Beam Piper, first published in Analog Science Fact-Science Fiction, in 1960.
